Choices: Standard vs. Compact Crankset

Finally a lot of the manufacturers are starting to make it easy to change between the two by just using an adapter and new chainrings.  That saves me a little anguish when it comes to choosing a compact vs. standard crankset.  I can just choose the one I think will be best without having to fret over a replacement cost of $300 - $700+.  I can't imagine that every single crankset manufacturer on the planet shouldn't be moving to this ability.

Just wait until 2013...
